I just bought the same set of monoblocks from Caxton Audio in Brisban. Enquired about biasing and whether or not directions are included for biasing and so on. They bias automatically. Assume you bought these from Simply Hi Fi. Ask Win. He's usually quite good about info and advice. Also, as part of the deal, I bought a quad of the Genalex Gold Lion KT88s. I currently use the same Gold Lions in a conrad-johnson MV-60SE amp (that has been converted to triode mode). They are very wonderful tubes.
I would be tempted to upgrade the 6SH7s as well. If you e-mail me, I might be able to help you out there.
